Use 9-micron SMF fiber for distances of up to 10
kilometers (6.2 miles). The specification requires
and specifies 5 kilometers (3.1 miles).
Use a conditioned launch cable to connect the
1000BASE-LX transceiver to multimode fiber. Using
this cable ensures reliability over the maximum 550 m
distance.
Cabling the 1000BASE-SX MMF Module
The 1000BASE-SX MMF module provides one Gigabit
Ethernet port that uses multimode fiber with an SC
connector.
To cable the 1000BASE-SX module:
1
Read and follow the “Fiber and Laser Safety
Precautions” on page 35 for safe operation.
2
Plug the male SC connector on the fiber cable into
the port on the Gigabit Ethernet module until it clicks
into place. See Figure 15.
3
Attach the other end of the fiber cable to the
network device that you want to connect.
4
Repeat steps 1 through 3 for additional Gigabit
Ethernet modules.
